Wiring circuit board

Abstract

A wiring circuit board includes a first insulating layer and a conductive pattern. The conductive pattern has a first terminal, and a wiring connected to the first terminal. The wiring has a first portion disposed away from the first terminal, and a second portion disposed between the first terminal and the first portion. The first portion of the wiring and the first terminal include a portion consisting of the first conductive layer and the second conductive layer. The second portion of the wiring consists of the first conductive layer.
